Purpose: In the present study, the effects of B4C reinforcement volume fraction (% 5-15-20) on the abrasive wear properties of AA2024 matrix composites produced with hot pressing methods were investigated. Design/methodology/approach: As-received samples were also used for comparison. AA 2024 powder was mixed with B4C-SiC-Al2O3 particles by a three dimensional mechanic mixer for 30 minutes. Mixed powder was pressed under 60 MPa at room temperature in the steel mold by unidirectional. Steel mold kept in the furnace at 550ºC after the pre-pressing for 30 minutes. Samples were pressed in heated mold under 100 Pa. The wear tests were carried out using a pin-on-disk wear tester by sliding at sliding speeds of 1.2 m/s against silicon carbide paper. Normal loads of 10, 20 and 30 N at constant sliding speed at room temperature. Findings: The experimental result showed that B4C volume fraction significantly influence the wear behavior of AA2024 matrix composites produced with hot pressing methods. Originality/value: It was also found that the wear resistance of AA2024 matrix composites produced with hot pressing methods increases with increasing B4C volume fraction. The highest weight loss was obtained in the unreinforced matrix material.
